The purpose of this investigation was to determine if a 9-wk youth soccer program had any effect on cardiorespiratory fitness (VO2max and VO2submax), peak knee torque, and flexibility. Subjects were 20 sixth grade boys, 11 of whom were members of a YMCA soccer team: 9 were normally active boys who were not participating in any organized sport during the study who served as a control group. Mean ages (+/- SD) were 11.8 +/- 0.34 and 11.5 +/- 0.60 yr for the soccer and control group, respectively. Initial VO2max values of 49.83 and 47.42 ml . kg-1 . min-1 for the soccer and the control group, respectively, are similar to those reported in the literature for untrained normal boys of this age. Results indicated that playing soccer three times weekly increased VEmax and reduced VO2 (ml . kg-1 . min-1 and 1 . min-1) at a submaximal running speed (all P's less than 0.05), while no change in VO2max was noted. No significant training effect was observed in peak knee torque or flexibility subsequent to soccer training. It is concluded that the effects of playing soccer in these subjects resulted in no change in cardiorespiratory fitness, peak knee torque, or flexibility.
本研究的目的是确定为期9周的青少年足球项目是否对心肺适能（最大摄氧量和次最大摄氧量）、膝关节峰值扭矩和柔韧性有任何影响。研究对象为20名六年级男生，其中11名是基督教青年会足球队的队员，9名是正常活跃的男生，在研究期间未参加任何有组织的运动，作为对照组。足球组和对照组的平均年龄（±标准差）分别为11.8±0.34岁和11.5±0.60岁。足球组和对照组的初始最大摄氧量分别为49.83和47.42毫升·千克⁻¹·分钟⁻¹，与文献报道的该年龄未受过训练的正常男孩的数值相似。结果表明，每周踢三次足球可提高最大通气量，并在次最大跑步速度下降低摄氧量（毫升·千克⁻¹·分钟⁻¹和升·分钟⁻¹）（所有P值均小于0.05），而最大摄氧量未发现变化。足球训练后，膝关节峰值扭矩或柔韧性未观察到显著的训练效果。得出的结论是，在这些受试者中踢足球的效果并未导致心肺适能、膝关节峰值扭矩或柔韧性的改变。
